This informative book examines some social entrepreneurs in practice in several countries whilst concentrating on entrepreneurs in the third sector. The authors call them citizen entrepreneurs. Such people are not only becoming more common but also more necessary in the world of today.Entrepreneurs are seen as people who aim `to act as if and make a difference', that is, who act out of the ordinary and come up with noticeable solutions to various problems without being restricted by existing resources or possibilities. This book applies these criteria to citizen entrepreneurs, focusing on public entrepreneurs operating in public places. The authors conduct in-depth case studies to examine these public entrepreneurs thoroughly and offer some theoretical reflections on social entrepreneurship.Students and researchers studying social entrepreneurship will find this book of great interest. Social entrepreneurs and practitioners would also benefit considerably from this enriching resource.
